The Los Angeles Times headline screamed: Rocket Scientist Killed in Pasadena Explosion. The man known as Jack Parsons, a maverick rocketeer who helped transform a derided sci-fi plotline into actuality, was at first mourned as a scientific prodigy. But reporters soon uncovered a more shocking story: Parsons had been a devotee of the city’s occult scene.

Technologically there's never been a better time to search for a new earth beyond our solar system.

How big is the universe? In the early twentieth century, scientists took sides. One held that the entire universe was contained in the Milky Way galaxy. Their champion was the strong-willed astronomer Harlow Shapley. Another camp believed that the universe was so vast that the Milky Way was just one galaxy among billions—the view that would prevail, proven by the equally headstrong Edwin Hubble.

"Die Lippen der Weisheit sind verschlossen, außer für die Ohren des Verstehenden." Mit diesem geheimnisvollen Leitsatz beginnt eines der einflussreichsten Werke der westlichen Esoterik: "Das Kybalion". 1908 in den Vereinigten Staaten von den anonym gebliebenen "Drei Eingeweihten"...

On February 20, 1962, John Glenn became a national star. That morning at Cape Canaveral, the small-town boy from Ohio took his place atop a rocket and soared into space. The Last American Hero is a stunning examination of the layers that formed the man: a hero of the Cold War, a two-time astronaut, a veteran senator, a devoted husband and father, and much more.  

There are approximately 25,000 "city killer" asteroids in near-Earth orbit—and most are yet to be found. Small enough to evade detection, they are capable of large-scale destruction, and represent our greatest cosmic threat. But in September 2022, against all odds, NASA's Double Asteroid Redirection Test (DART) mission deliberately crashed a spacecraft into a carefully selected city killer, altering the asteroid's orbit. In How to Kill an Asteroid, award-winning science journalist Robin George Andrews reveals the development of the technology that made it possible

Florida's Space Coast tells the compelling story of America's half century in space exploration from the successful launch of the first two-stage rocket in 1950 through the space shuttle missions of 2000. Told from the unique viewpoint of the people who built the Spaceport, this book shows how the space program transformed the east central Florida coast from a traditional citrus production and tourist area to one of the most influential high-tech centers in the nation.

This classic in the field of ufology is filled with hard-hitting eyewitness testimony of one of the most important events of all time: the actual recovery of a UFO outside of Roswell, New Mexico, in 1947. For more than seventy years, government authorities have led us to believe the wreckage was merely a very conventional weather balloon - but the witnesses who were there continue to tell a different story. Witness to Roswell once again provides a "can't put down" written account of what really transpired in Roswell decades ago. 

The heart of this course examines the planets themselves, and reveals how they are constructed and how they differ from one another. By studying the physical astronomy of all the planets in the Solar System, we can attempt to understand their true nature. Ultimately, these lectures will bring us to a greater understanding of the Solar System's creation, which brings us again back to the beginning and what it means to us as we look outward from our rotating Earth.

A four-star general pays tribute to a remarkable man in this biography. Believing that America owes a debt to a great character, a superb aviator, and a devoted citizen that was not paid, General Kenney tells the story of Paul Irvin "Pappy" Gunn with the hope that it will help discharge some of that debt. Gunn, who was known during World War II as an expert in daredevil low-level flying and as a hero and mechanical genius, modified light and medium bombers and transformed them into attack aircraft to hit Japanese targets in New Guinea, the Philippines, and Okinawa.

What is a meteor or meteorite? A meteor is a small bodastrony of matter apparently from outer space that upon entering the Earth’s atmosphere resembles a streak of light, what we normally call falling stars. A meteorite is one of these that successfully hits the ground and sometimes other things, including people, buildings and animals! Until 1803 most scientists regarded falls of meteorites as absurd and fantastical. As well as impossible. This was until the massive fall onto L’Aigle in France of thousands of meteorites on April 23rd 1803.

A respected physics professor and author breaks down the great debate over the Big Bang and the continuing quest to understand the fate of the universe. Today, the Big Bang is so entrenched in our understanding of the cosmos that to doubt it would seem crazy. But as Paul Halpern shows in Flashes...

A sweeping inquiry into how the night sky has shaped human history For as long as humans have lived, we have lived beneath the stars. But under the glow of today’s artificial lighting, we have lost the intimacy our ancestors once shared with the cosmos. In Starborn, cosmologist Roberto Trotta...

Stargazing has shaped the entire course of human civilization. The rhythm of our ancestors' lives revolved around the stars, from cycles of agriculture to patterns of birth. How radically different would humanity be if our ancestors had looked up to the night sky and seen...nothing? In lyrical yet evidence-grounded meditations, Trotta imagines a world without stars, a dramatic alternate history in which we wouldn't understand gravity, where couldn't navigate or have much sense of time, and where our sense of the profound - of art and of the divine - was altered beyond recognition.
